Clevo P3xx SM / refresh system question

What's the difference between these 3 models? Which one is the oldest/newest?

P370SM, P370SM3, P375SM

Why is there a "P377SM-A"? Where does this model fall in Clevo's lineup? Why is there an "-A" suffix?

From the three models (and p377sm-a), which one support pure UEFI GPT boot with 980M (single) on windows 7?

If the machine comes with a 8-series GPU such as 860m, 870m, 880M. Can a 980M be a drop-in upgrade without buying extra heatsink?

Where can I find 3 pipe cpu heatsink and the secondary gpu fan?

Finally, what downsides do you get from getting a QS CPU (4920xm) compared to retail 4920xm?

Thanks in advance.

 

3-pipe cpu heatsink comes from P370EM models, but then you have to sacrifice slave GPU cooler temps.

I have P370EM GPU heatsinks (slave and master) if interested

 

- P370SM is the clean base model
- P370SM3 has 3D for GTX7 cards and comes with 120Hz screen and inbuilt 3D emitter.
- P375SM has a slightly different design and comes with additional 'flasher-lights' on the backside of the unit (IIRC)
- SM-A model is the generation after the SM and mainly has an updated EC controller and additional audio chip among minor board changes.

 

Along with clearing up any issues with the 2nd mSATA slot for the -A.

 

Ok, thanks for the info. I plan on using the 3-pipe CPU heatsink without any slave GPU heatsink (no Slave card installed), is this possible?
So the final config would be the CPU being cooled by 3 pipe + 2 fan (cpu fan, slave gpu fan).



What's the risk of getting QS XM cpu? And can a 980M be a drop-in upgrade for 860M heatsink?

I only have 1x 980M, this machine will work with only 1 card (master) right?

 

QS CPUs can be different steppings to retail (so can have additional errata) and are not supposed to be sold (ever). Otherwise they can function just like the real thing.

There is a blank plate supposed to help that configuration that supports the third heatpipe arm.

 

You should be fine with the CPU.. Not sure about GPU heatsink but you probably need a proper 3 pipe one I believe? As for the QS CPU, it might not have proper temp sensors but on the whole, ask as many questions to the buyer before buying..

He has a heatsink for the primary card but wants the shared CPU heatsink without the 2nd card or 2nd GPU heatsink.

 

Just for info i also got a 4900qm QS. It works perfectly and temps with liquidultra seem good. Only bad point is i cant overclock it more than 39 38 37 37 or i got a bsod. I think i m not good enaught with voltage settings and so on..

About sharing heatsinks, will be a bit complicate because they are at 15-20cm between both. You will have to kinda create a large copper-bridge between them.

 

Every CPU is different, but have you tried 38,38,38,38 ?

 

for supporting some 60fps video in 4k, cpu need to be at 3.9GHz. if down of this, i have some break flash time while watching. Some videos.., others working perfectly.

 

When I was experiementing with overclocking my 4800MQ, this was one of the last things I tried and it was pretty stable. Once a month it would fail to POST when clocked like this, though I believe that's because of XTU. I was in the habit of using it over the BIOS, which I've learned to stray from it since.

 

Usually if you care more about the quad core being all active then having none of the others higher lets you keep the voltage down as a single core running at 3.9ghz needs more voltage than a quad core at 3.8ghz.
